Do I connect positive to positive?
The positive (red) cable should be attached to the positive terminals on each battery. Attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery. Attach one black jumper cable clamp to the negative terminal of the working (live) car’s battery.
What happens if you hook up a jumper cable wrong?
You might cause personal injury and/or damage to your car if you accidentally hook your jumper cables up wrong. Fuses (and/or fusible links) act as circuit protection devices between the battery and the vehicle’s electrical system.
What happens if you hook a battery up the wrong way?
Depending on how long it was connected the wrong way the battery may survive and just need charging but the chances are it needs replacing. You would have also most certainly blown some fuses, look for some big ‘mega’ fuses connected directly to the positive cable. Not the answer you’re looking for?
What happens when you reverse a battery cable?
Reversing the battery cables creates a surge of electrical current that can easily damage the battery. When you reverse the polarity of the jumper cables, you create a drastic increase in the amount of electrical current that runs through them.
What’s the difference between positive and negative jumper cables?
The positive jumper cable should attach both batteries’ positive poles while the negative jumper cable attaches the two negative battery poles.

What did I do when my jumper cable melted?
The cables are melting!” I ran out and found exactly what she said. One of us turned the van off. I then disconnected the jumper cable leads and threw them to the ground because they were hot. But, the damage was done. The insulation on the jumper cables had portions melted off.
